Both the SAT and STL files are in CAD format so that means they should be coverable. The trick would be to find a program that supports both of these file types. One of such programs is a dedicated CAD converter called CrossManager that supports huge number of various CAD formats and can perform conversion between them.

The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned sat to stl. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
